Arizona Rep. Paul Gosar tells Newsmax.TV that he would support a lawsuit blocking the Obama administration from initiating its plan to grant amnesty to certain children of illegal immigrants.

“I will and do. You know this is an overreach by the president in regards to the privileges of Congress and Congress only,” Gosar, a Republican member of the House Oversight and Government Reform Committee, tells Newsmax in an exclusive interview. The U.S. Constitution, he said, gives that “jurisdiction for naturalization and enforcement to Congress and not the president.”

Iowa Rep. Steve King has said he would sue the White House to block the immigration plan, which affects illegal alien children who came to the United States before their 16th birthday. The June 15 executive order mirrors the DREAM Act, which is popular among Hispanics and was defeated in the U.S. Senate last year.

When asked whether the move by President Barack Obama was merely an election-year ploy for votes, Gosar replied: “It is. He’s defying the Constitution – and we are seeing this in front of our eyes.”

“You know he’s desperate to try to be re-elected — and he’s doing anything and everything, including defying and defiling the Constitution at any point in time to be re-elected.”

Gosar continued to accuse the White House of declaring “war on Arizona” via measures it has taken against the state since the U.S. Supreme Court upheld its controversial immigration law. The Obama administration has cut funding to the state and has shifted federal border-patrol agents from critical locations.

“I’m a little sick and tired of it,” Gosar said. “Not giving the financial support and moving border-patrol agents to border crossings instead of where they’re needed and deserved.

“But we need to uphold the rule of law. And I’m a little sick and tired of the way that they administration has declared a war on Arizona — and be careful if you start a war with Arizona. We just may finish it.”

He also expressed support for Maricopa County Sheriff Joe Arpiao, who is on trial for allegedly discriminating against Latinos.

“Once again, we have put our law-enforcement folks in harm’s way by putting them in double jeopardy,” Gosar said. “I applaud Sheriff Joe for following the rule of law and enforcing all policy in regards to requiring documentation.

“And this isn’t just about the Hispanic population: This is about everybody,” he added. “When I sit and vote on the House floor, I need my picture ID. I need my PIN [number] to go to see Attorney General Eric Holder. I need a physical ID that shows our government-issued ID.

“There’s something wrong when you have the attorney general and the President of the United States not upholding the registration of people that are documented to be in this country properly.”

Gosar endorsed a complaint filed earlier this month to Holder disbarred. The move to the Office of Bar Counsel in Washington was undertaken by gun-rights advocates and two bloggers who have reported on the failed “fast and furious” gun-running scandal.

Holder, a Bar Counsel member, was cited for contempt last month by the U.S. House of Representatives.

“That is appropriate, because we need to make sure that people are held to the same letter of the law that everybody else is,” Gosar said. “I don’t think this is the end. I suspect we’ll see more subpoenas in trying to get more documentation and information.”
